In modern reprints, the names of the children have been changed - from Jo, Bessie and Fanny to Joe, Beth and Frannie - in the first case to make it clear that Jo is a boy, in the second because Bessie is seldom used as a nickname for Elizabeth anymore (most would go by Beth, Liz or Lizzie), and in the third because Fanny is a slang term in the United Kingdom (see Wiktionary entry). Cousin Dick, who appears in "The Magic Faraway Tree", has his name changed to "Rick" in new editions, presumably for similar reasons.
